24 PLANTS BAKERIAN^E. 



and almost glabrous, these many, only J inch long but 

 rather exceeding the internodes, spatulate-obovate, obtuse or 

 some of the earliest obcordate-notched, entire, those below 

 the inflorescence with some fascicled smaller ones in their 

 axils, the upper with Ir to 3 flowers in their axils: calyx 

 parted deeply into linear-liguliforin abruptly acutish and 

 minutely ciliolate lobes: corolla elongated and narrow; 

 anthers glabrous. 



Forming large mats on open slopes at Keblar Pass, 7 

 Aug., n. 733. The species is related to P. csespitosus. It 

 may possibly be identical with Gray's so-called var. suffru- 

 ticosus of that species; but of that I have seen no specimens,- 

 and the description is insufficient for the identification of a 

 species. 



COMPOSITE. 



SENECIO CONTRISTATUS. Stems several, stout, erect, 2 feet 

 high or less, leafy up to the simple raceme of several large 

 nodding rayless heads: lowest leaves with an elliptic blade 

 3 inches long and a broadly winged petiole half as long, 

 the cauline more lanceolate, subsessile or 'sessile, all closely 

 callous-denticulate, scaberulous between the callosities, other- 

 wise glabrous, like all other parts of the plant: heads broadly 

 campanulate, f inch high, the lanceolate acute bracts of the 

 involucre of a very dark red-brown, the inner ones with 

 obvious yellow scarious margin: rays none, disk light-yellow. 



In small clumps on open ground at Keblar Pass, 14 Aug., 

 n. 787. An interesting addition to that small group of 

 Rocky Mountain species marked with few and large rayless 

 heads. This one is, however, more nearly allied to the 

 southern S. Rusbyl than to its near neighbor, 8. scopulinus. 



SENECIO PYRRHOCHROUS. Erect, stoutish, 2 feet high,
